.llaving reference to the drawings,-at 1, Figs. .1, 2, etc., is the side-frame at the driving end ot the/loom, 1 in Figs. 3, t3 and 7 being" the side-frame at the replenishing end.

At 2, Figs. 9., (3, 7, etc., is the breast-b am. lhe cranleshat't of the loom is shown at 3, Il igs. 1, 2 and 3, and the cam-shaft at 4.. the usual gears by which motion is transmitted from the crank-shaft to the camshaft being shown at 5, '6. Having reference to the driving.connections, and to the shipper and brake devices of Figs. 1 and'Q, a loose bandpulley 7 is mounted upon and the eranlesharlt .3,

At It is a clutell-operating lever which is pivoted at 'ltll upon a stand 1 Figs. 1 and 2, attached to loom-side] and extending outward therctrom, the said lever having" a fork whiclnenganes with a yolte il in connection with the hub T] ot the loose taunt-pulley T. A rod It connects the clutch-operating lever to with the upwartlly-extemling arm of a bcllcranlt 12 which is mounted upon a stud lQl carried by and projecting outward from tho loomside I, it having}; a forwardly-extending arm 112:2 by means oli which it. may be operated for the purpose ol acti'lating' the lever U) to more tllc band-pulley 7 toward and from the wheel l as required in order to close and open the trlctitill-clutch.

1;; is a ln-al-rc-whecl which is lixed the cran'leslmtt. It, and which extends partly around the periphery of the said bralw-wln-el. one end of the said brake-lnnnl being connected to an adjustable eye-bolt to that is carried by a stand 151 projecting from the loom-arch, while the other end ot the said lu'akcdiaml is connccttal with the upwardly-extendinir arm of a bell-crank 16 that is mounted upon the said stud 121,, the said bell-crank having a torwardl vcxtcnding arm 161, the 'lorward extremity ol which constitutes a. handle. whereby the bell-cranlt 16 may be manually operated when desired. To the said arm ltil is connect'tal one end ot' the strong: contract in; spiral spring l'i', the other end of which is connected to an eye-bolt 17] that is ourricd by a stand lb projecting from the loonn side 1. Normally the arm 161 of bell-crank it? is held upraised with the bell-crank oecupying a position in which the brake-band is slack around the brahewvheel l3. \Vhcn the bell-crank Ill is freed to the said spring 17, the latter opcratts the bell-cranl to tighten the ln'ahe-lmnd it upon the peripheny ol. the bra lte-wheel. ln order that the movement of the belbcranl; 16 under the action ol the spring may also transmit movement to the clutclropcraling lever 10, to open the clutolr and thereby diseonnect' the driving power. the arm [til upon members of a 'l'riction- It is a brahc band the control of 100 end of the'breast -beam at the bell-crank furnished with a pin 162, which projects transversely from the said arm across the top of the 16 is operated by its spring 17, the descent of arm :161 causes the arm 122 of bell-crank 12 to be pressed down by the said pin 162, thereby transmitting to the clutch-operating lever 10 movement 1n the direction to separate the clutch-members and thus discontinue the application of drivingower. For the purpose of. enabling the bell-cranks 12 and 16 to be operated simultaneously in starting a loom, so as to throw off the brake and effect the clutching of the band-pulley? to the crank-shaft, the arm 122 Y of the bell-crank 12 is furnished with a later-- ally-projecting pin 123, Fig. 1, which extends through a slot 191 formed in the lower end of a rod 19, the said slot extending in .thedirection of the length of the rod, the upper end of which latter 1s pivoted at 192 to the shipper-handle 20, which last causes therod to move endwise, and by engagement of the wall at the lower end of slot 191 with the pin 123 the bell-crank 12 is turned to clutch the band-pulley 7 to the crank-shaft, the engagement of the arm 122 of the said bell'crank with pin 162 on arm 161 of bell-crank 16 causing the latter bellcrankito be turned so as to slacken the brakeband. In the position normally occupied by the shipper-handle during the running of-the loom,

I the point of connection 192 between the rod 19 and the shipper-handle is slightly forward of the center of the stopping rock-shaft 21, whereby the parts are lockedv in working position. When the shipper-handle is moved reversely so as to carry the said point of connection to the rear side of, the center of rock-shaft 21, the

spring 17 acts to move the'bell-cranks to J to" instrumentalities.

When the change-shaft is caused to rotate, a preliminary movement of the injector toward the front of the loom occasioned by cam 243 carries the injector against a downwardly-extending finger 232 of the shuttle-support, moving the latter forward'so as to Withdr w its rearwardlyextending fingers from beneath thebottom .shuttle in the hopper and permit the contents of the hopper to drop until the bottom shuttle rests upon the horizontal shuttlesupporting portions of the injector. The

j'ector .in the oppositedirection, namely for- :warditoward the breast-beam, and thereby restores the injector to its n'ormalposition shown in Fig. 3.

At 26 is the at the replenishing end of the loom, it being movable to enable the same to'be withdrawn from its normal position at thefront of such shuttle-box, to open the box to permit the spent working shuttle on the lay to be discharged from the shuttle-box and a fresh or reserve shuttle to be insertedinto the latter front-plate of the shuttle-box through the action of the injector. The

jectiug arms 261, 261, forming part of. a rocker 262, vthe rockshaftof which last is pivotally mounted in bearings that are provided .in brackets 263,- 263, which are attached to the lay-beam and rise at the rear thereof, Normally the front plate 26 is held depressed in its working position, so as to keep the shuttle-box closed, by means, of a contracting spiral spring 264, Fig. 3, having one endthereof connected to one of the forwardly projecting arms 261 of the r cker and the other end thereof connected to'hne of the brackets 263. For the purpose of operating the 'rocker to raise the front-- plate .to open the shuttle-box to permit of the discharge of the spent working shuttle and theiintroduction of afresh or reserve front plate 26 is carried 'by forwardly-proshuttle, the rocker is provided with a rearwardly projecting arm 26.) having connected therewith one end of a connecting rod 20c, the opposite end o't' which is connected to an arm 267., which is pivot-ally mounted at 268 and provided with a projection that is engaged by the periphery o:t' an edge-cam 269 which is fast upon the ehangesha'lt. In the rotation of the change-shalt, the cam 269 transmits movement through the arm 267 and coin'iecting rod lot; to the rocker to raise the front-plate trom its normal closed position and thereby open the shuttle-box. The spring Eli-"l.- acts to move the rocker in the reverse direction under the control of the cam 269, to lower the front-plate to its normal position and thereby. close the shuttle-box again. An ejector 27 is mounted by means of brackets 5271, i271. upon the hack of the shuttlel; 0x, the said ejector being formed as a rocker having journals which are titted to hearings in the said brackets, and having lingers which project: into openings at the rear of the shnttle-box as indicated in l igs. 3 and t. The ejector is held retracted normally by the tension of the contracting spiral spring 272, the latter ha ving one extremity thercot engaged with a screw or the like projection carried by the rockshatt of the ejector, while the other end of the said spring connected with a strap that wraps part, way around the rockshalt of the ejector and is attached by its inner end to the said I'Oflh'HlltlFt'. linger 27;!

projecting from the ejector takcs against the under side of the roekshatt; ot' the rocker 262 and serves to limit the extent of the retraction of the ejector under the action of the spring 272. A finger it' l: projecting forwardly from the ejector is pressed against by one of the arms .261 ot' the rocker 262 in the moven'icut oi the rocker by which the front-plate ot' the shuttle-box is raised, and thereby the ejector is actuated to eject the spent working shuttle from the opcucd slnitt'lcbox,

At; 28 is a. llexibl: apron onto which the ejected shuttle l alls the said apron litllltf connected at its upper end with the trout ot' the lay-beam and passing torward over a transverse rod 281 which is supported at the rear of the shuttlorccciving box 5263, the latter being attached to the adjacent sidcframe of the loom. The shuttle slides l'rom the apron into the said box. The apron plays back and forth over the rod 28] as the lay vibrates, and thereby acconnnodatcs itself to the varying positions of the lay, it. serving to conduct the ejected shuttle into the box 282 whatever may be the position of the lay at the time of the ejection.

The chango shalt. normally stands at, rest. For the pertormancc oi the replenishing operations the change-shaft with its various cams is called into action. A dwell in the \vmking ol 'the weaving, instrumentalities is brought about by causing the braking devices to unt'lntch the band-pulley 7 from tho wheel 5). and by also causing the braking dcviccs to apply the brake. ()n the conclusion ol' the replenishing operations the said weaving instrumentalities are restarted by again clutching the band-pulley to the wheel 1 and taking oil the friction of the brake, al'lcr which the change-shalt comes to rest.

The means ol"comnmnitalling rotary motion at the proper time to the change-shaft, and subsctpicntly discontinuing such motion, is shown in Figs. 1.1: and 5. in Figs. '1 and 2 the loose hand-pulley T has 'l'ast. therewith a beveled. gear Tltl meshing with a bevel pinion 72 which is last upon the upper end ot an inclined shaft 73, the said shall. at. its lower end being :t urnished with a worm 74 meshing with a worm-gear that is mounted upon the change-shalt .45 with capacity to turn :t'rccly thereon. .lhrongh the driving connections between the loose pulley T and t'he '-.vorm-gcar 75 the latter is constantly rotated. During the ordinauv running of the loom, this rotation ot the wormgcar is umiccompanicd by motion of the clmngc-shal't. When the change-shall and its cams are required to act, the worm-gcar is clutched to the changc-shal't. To enable the clutching to be t-ll'ected a disk 25], Figs. 53 and 5, istixcd upon the cliangwsha'l't, with the outer tat-c thereof close to the inner face ot' the worm-gear. To the inner t'ace of the said lixcd disk 3531 a clutching-lever is pivoted at 2533, Fig. 2. Said lever extends diametrically with relation to the disk 251, and swings toward and from the disk. ()nc arm of the said lever is furnished with a projection 251 working in a. hole that is made through the disk. In the worm-gear 75 is Ilormcd a circular serics oi holes 751., 751, etc, Fig. 1, each adapted to receive the projection 5351 when in line with the latter. The lever 252 is acted upon by a spring 256, the lattcr tending to turn the lever into a position in which the projection 25 shall project through the disk 25] and enter into one ol' the holes 751, 75], of the worm-gear 75. la the present instance a single spring, Zoo, is employed it having its ends engaged with opposite portions of the disk 253i, and its intermediate portion passing back of the tail portion ol' the clutchingdcvcr .552 so as to d aw by its coils against the back ot the said laihportion with a tendency to press the said tail-portion to 'aid the disk. So long as the lever occupies a position with its projcttion withdrawn from thc worm-gear 75 into the hole .655 the worm-gear is free to turn pon the change-shatt independently ot the latter. and the change-shaft remains motionless. The lever is held normally in its witlnlrawn or disengaged position, against; the tendency of the spring 256 to 45 begin to rotate.

50 or normal. position,

55 thereof, the replenishment having efi'ectuated, the tail of lever 252 is earned &

turn the same so as to carry the projectionv 254 toward the worm-gear 7 5,.by means of "an unclutching arm 257, Figs. 2 and 5, which is pivoted at its lower end upon a 5 fixed stand 258,its upper end being obliquely and the other end thereof joined to theouter portion of stand 258. The said spring is arranged to cause its action to take place along a line inclined downward and outward, the

result of which is to force the unclu'tching arm 257 outward toward the disk 251 and also draw the latch downward and hold it in engagement with the shoulder 260. Normally, the acting portion of the arm 257 remains in engagement with the tail of the: lever 252," holding the said lever turned into the inoperative position thereof, with its projection 25 1 withdrawn from engagement With the worm-gear 75. WV hen, in the working of the loom, the latch is raised so as to d1sen gage the same from the fixed shoulder, at

which time the action of the lay and other weaving instrumentalitieshas been arrested by causing the shipping rock-shaft 21 to be so turned so as to bring about the action of .35 the shipping andbrake-mechanism to unclutch the loose band-pulley and apply the brake, the spring 256 acts to turn the lever 252, pressin .back the arm 257 against the resistance o the weaker spring 2601, and

carrying the projection 254-. toward wormgear and into that one of the holes 751 which first arrives in line with the'projec- 1 vtion. Thereby the worm-gear is clutched to the change-shaft and the latter is eausedte As soon as the rotary mo-'.

' tion of the change-shaft has carried the tail end of lever 252 away from the engaging portion of the unclutchin arm 257, the spring 2601 restores the sai arm to its outer and causes the latch 259 to engage again with the fixed shoulder 260 so as to hold the arm against tendencylto 'movement inward. As thechange-s aft approaches the completion of one rotagion ecn into contact with the engaging portion of the arm 257, which arm at this tune is latched. firmly in position, and by. such con- 1,60 tact the lever is turned to disengage its vprojection 254 from the worm-gear, thereby unclutching the changeshaft from'its driving mechanism.

The devices for 'estarting the weavmg .65- instrumentalities a ter, replenishment comprise the cam 29 on the change-shaft 25, the lever 291 pivoted at 268 and having a projecting portion which is held pressed against theperiphery ofthe said cam by the action of thecontra'cting spiral spring 292, a rod 293 which is provided with an adjustis produced by the action of the prominence of said cam, an arm 295 which is mounted loosely upon one end of the'ship-per rock- 296 which is fast upon the said',rocl:shaft, and a stiff spring 297 connecting the said mit motion with yielding force from arm 295 to arm 296. The said spring yields to avold breakage in case the shipper rockrestzirting mechanism at a time when the dagger of the protector mechanism is in engagement with the frog. The cam 29 acts, through theconnections which have been described, to turn the shipper rockshaft in the direction-to replace the'shipper-handle in 'the position which it occupies during the regular running of the loom, and also oper? ate the ship ing mechanism'to clutch the band-pulley 'ihvlth the fixed wheel 9, as well as relieve the pressure of the brake 14 upon the brake-wheel 13. As the 'unclutching of the worm-gear 75 takes place, the projection of arm-291 enters a notch 11 in the periphery of the cam 29, thereby locking the changevshaft against accidental motion, with the tail' of the clutching lever 252 remaining in in inoperative position.

fork 30 which is located at the replenishing end orside of the loom, the slide or carrier 31 on which the said weft-fork is pivotally mounted, the guide 32 for said slide or carv rier secured by a screw 33 to the breast-beam 2, the weft-hammer or gooseneck 34 cothe cam 35 upon actuated. For the purpose of tripping the .weft-replenishing instrumentalities into action or detection of weft-failure b the weftfoi-kBO, the slide or carrier 31 oi: such fork has applied to the front end thereof a stud 3451 .projecting'forward and provided in its forward end with a transverse hole or slot receiving a. starter grin351.projecting laterally from an arm 6 rising from a rod37 on which such arm is fixed. The rod 37 is supported in" front edge of has v crosswise to the loom. At one endthereof shaft'21 and with which the forward end of the. rod 293 is connected pivotally, an arm- .arms' with each other-and serving to trans-- shaft is prevented from being turned by the engagement with the unclulching arm 257, 'whereby the said clutching lever is retained The weft detector devices which are shown 1n the drawings comprise a, weftoperating with the said weft-fork 30, and

cam-shaft 4 by means of which the weft-hammer or gooseneek is been completed are shown in Fig 3, and

able collar 294 to be engaged by the said lever 291 in the movement of the latter that osition adjacent the lower t e breast-beam, and extends it is fitted to a bearing 871, Figs. (3 and 7, which is attached to the breast-beam. The other end of the rod enters the central eye of the hub of arm =11 hereinafter described, and tits loosely therein, whereby such end is SllppOll'CCl. Upon the latter end an up wardly extcrnling arm 38 is lixed, the upper end of said arm being provided with a latcral projection or stud 392 upon which is pivotally mounted a dog; 39 having a lateral engaging projection 391. The said projection extends over the upper end of the arm 11, the latter rising from a short rod 111 which is supported .in line with rod 237 by a fixed bearing 112, the arm -11 being tixed upon the inner end of the said rod 11.1. The said upper end of arm 41-1 is provided with a shoulder 12 with which the projection 391 is adapted to engage. l'Vhen the rod 37 is turned or rocked :lorward in mmswpieime oli the advance of the welt-tort; slide or carrier 31, the result of; such engagement of pro jection 391 with shoulder 1., is to rock the arm 11 and rod 411. For the purpose of controlling the replenishing instrumentalitics, the rod 111 is furnished with an arm 42 projecting rcarwardly therefrom and joined by a flexible or other connection 14 with the latch259, so that when the parts are rocked as just mentioned the said latch discugaged from the fixed shoulder 260 and the unclutching arm 257 is unlatchcd or unlocked, allowing the spring 256 to turn the clutching lever 252 and clutch the wormgear 75 to the change-shaft. For the purpose of t ansmitting movement to the shipper-handleQO to bring about the stoppage of the weaving instrumentalities with the shuttle in the shuttle-box at the replenishing end of the loom, the rod 111 has fixed thereon a hub 15 having a projection 4:6 for engagcment with a projection 47 of the ship-' per-handle. Vhen rod 111 is turned as aforesaid, the action of projection 416 againy projection 17 operates to turn the shipperhandle to carry the line of draft that is transmitted by means of the rod 19 from the brake-lever 12 to the shipper-handle 20 over to the rear of the center of shipper-rockshatt 21, unlocking the shipper-devices, whereupon the spring '17 acts to etl'ectuato the unclutchin of the band-pulley 7 and the application of the brake.

In accordance with the invention, I make provision against accidental starting-up oi? the change-shaft during an ordinary stoppage 01: a loom. The reason for this is the fact that the worm-gear 75 is driven constantly from the band-pulley 7 so long 2 the driving-band 8 which passes around said band-pulley is in motion. It is importantto provide against starting-up of the changeshaft in consequence of the action of the Weft-fork mechanism while the loom is being turned by hand during stoppage, as he quently the case in practice. In this embodiment of my invention 1 furnish the dog 3!) with a prolongation or extension 395, l igs. (S, T, H and J, extending downward therefrom, and l mount upon the shipperrorloshal't an arm or finger 396 which is setscrewcd to the said roclcshat't and provided at its tree extremity with a transverse projection 397 suitable to make contact with the said prolomration or extension when the said rockshal't is turned for the purpose of .(mcmaioninn a stoppage of the loom mechanism. The action of the arm or linger 396 against the prolongation or extension 395 turns the said dog 3!) upon its pivotal stud 392 on the arm 38, raising the engaging projcction 391 of the said dog above the shoulder 12 of the arm -l.1. The rod 37 may now be turned, as in consequence of the action of the wcttlorl; mechanism, without affecting the arm 11 and rod 411, and consequently without bringing about the disengagement of the latch 259 from the fixed stop 260,
